- A prior art mobile phone is generally held close to an ear by a hand for use. This will cause much inconvenience in use or may even bring about an accident when a user drives a car or rides a motorcycle. Moreover, a mobile phone in use will emit high-frequency EM waves of high power to cause damage to the human body. Therefore, handsfree mobile phones have been proposed. Handsfree mobile phones can generally be divided into the car-type and the personal-type. A car-type handsfree has a transmission line connected to a mobile phone and a power line plugged into the car lighter. A personal-type handsfree is generally a wired device. Although it can reduce the danger in driving, there is still inconvenience such as entanglement of wire or bad contact due to pull and drag of the wire in use. Moreover, because entanglement of the connection wire blocks some space of the gear shift lever, the user may erroneously touch the handsfree or even damage the mobile phone due to pull and drag of the wire.
- Because the prior art handsfree mobile phone has inconvenience and drawbacks in practical use, wireless earphones have become available in the market. A mobile phone base matching the wireless earphone is usually disposed on the mobile phone. The wireless earphone is hung on an ear of a user. Although wireless transmission can solve the problems of entanglement of wire and harm to the human brain due to high-frequency EM waves, there is still no wireless earphone integrating the functions of handsfree mobile phone, music player, and broadcasting device.
- One object of the present invention is to provide a multifunction audio wireless transmission device and a wireless earphone, which integrates the functions of a handsfree mobile phone, a music player, and a broadcasting device through a broadcaster, a speaker, and a plurality of push-on switches built in the circuit thereof.
- To achieve the above object, the present invention proposes a multifunction audio wireless transmission device and a wireless earphone. The multifunction audio wireless transmission device comprises an audio transmission interface connected to the mobile phone to receive an audio signal output by the mobile phone, a signal processing unit connected to the audio transmission interface to receive and then process the audio signal, and a wireless transmission unit connected to the signal processing unit and the wireless earphone to send the processed audio signal to the remote wireless earphone and receive an answer signal output by the wireless earphone. Bidirectional audio transmission between the wireless earphone and the mobile phone is thus accomplished via the audio transmission interface and the wireless transmission unit.
- The wireless earphone comprises a control and processing unit connected to a broadcaster, an output unit, a microphone, a wireless transmission unit and a push-on switch unit. The push-on switch unit outputs a control signal to the control and processing unit. The control and processing unit controls the wireless transmission unit to receive an audio signal output by the multifunction audio wireless transmission device. The control and processing unit processes the audio signal and then sends the processed audio signal to the output unit. A user can utilize the microphone to input voice messages, which are processed by the control and processing unit and then sent to the multifunction audio wireless transmission device via the wireless transmission unit. Bidirectional audio transmission between the wireless earphone and the multifunction audio wireless transmission device is thus accomplished via the wireless transmission unit.
- The push-on switch unit outputs the control signal to the control and processing unit to control the broadcaster, which outputs a broadcast signal. The broadcast signal is a stereo sound signal. The broadcast signal is output to the output unit. The output unit receives the broadcast signal and then converts the broadcast signal to an output sound signal.
